SPECIFICATION forming part of Letters Patent No. 644,108, dated February 27, 1900. Application i165. September 28,1899. Serial No. 73l.,956. (No model.)

To all whom it may concern,.-

Beit known that 1, CARL FRIEDRICH PHIL- Irr STENDEBAcII,a subject of the King of Saxony, residing at Leipsic, Kingdom of Saxony, Germany, have invented `a certain new and useful Improved Electric-Car-Contact Device for Underground Conductors,of which the following is a description. y

The present invention relates to motor-cars 1o driven by electricity, and more particularly to the mechanism for making and breaking the current between the lfeed-line and the contact-heads'of the sectional conductors each time the 'car passes over the line, as de- !:5 scribed in my application for patent Serial No. 691,371. (Patent No. 633,166, dated September 19, 1899.)

This device is for use in connection with cars fed from underground conductors, and 2o consists of a contact-disk mounted in proximity to the contact-heads, over which the car passes and from which it is fed with electricity, the contact being made by means of a rotary disk, which is oscillated to make con- 2 5 tact as soon as the frontend of the car reaches it and to break the contact to the head-as soon as the rear end of the car passes, the said mechanism being operated by means of a plow or runner 011 the car, which runs in a 3o suitable channel provided for the purpose.

In the device covered by the application above mentioned the runner on the car operates to make the contact, which is broken by means of a spring or Weight after the runner 3 5 has passed by. The object of the present invention is to provide means for positively breaking as well as making the Contact.

In order to render the present specification easily intelligible, reference is had to 4o the accompanying drawings, in which similar numerals of reference denote similar parts throughout the several views.

Figure 1 is a section through the contactboX, taken in the vertical plane. Fig. 2 is a horizontal section taken in a plane below the contact-disk and showing the mechanism for positively actuating the same. Figs. 3 and 4 represent, in side elevation and part plan,

diagrammatic views of a car provided with` the means for operating the device.

The disk 9 is adapted when oscillated to make and break contact between the main conductors and the sectional conducting-heads to the car-brush, as specified in the patent application above referred to. This disk is mounted on a vertically-disposed shaft 3. in which the contact is made and broken is not Vdescribed here, since the same is indifferent and has nothing to do with the present invention. The shaft 3 is provided with crank-arms 23 23, arranged in different horizontal planes, each being connected b v a pinand-slot connection toa horizontally-guided bar 4, guided at one end in the lugs 22 ofthe housing and at the other end passing through the wall of the channel 7 vand provided with contact-rolls 5. The car is provided at the front and rear ends with plates 24, which hang down into the channel 7 and are provided with cam-surfaces, Fig. 4, arranged in corre- The manner Y sponding horizontal planes and adapted to contact with the rolls 5 of the bars 4. The said bars are so mounted and connected up to the cranks 23 that when the upper bar is pressed inward by the cam on the car the lower will be forced out, and vice versa.

The device operates in the following manner: When the front plate-cam passes the roll 5 of the bar 4, which projects into the `channel 7, the same pushes the said bar back and turns the disk 9 to establish contact between the main conductors and the sectional feed-head, and the parts remain in this position until the rear plate-cam operates the other roll 5, which was projected by the inward movement of the first roll, and thus breaks the contact again as soon as the car has passed the feed-head.

I claim as my invention- 1. In a device for supplying electricity from the main conductors of an underground feed system, to the feed-heads for the cars, comprising an oscillatory disk for making and breaking the contact between the main conductors and the sectional feed-heads, means for positively oscillating the said contactdisk in both directions from the carin the manner and for the purpose substantially as described.

2. In a contact device as specified, the coin binat-ion of a contact-disk to oscillate to make and break Contact, a shaft to which said disk is keyed, cranks on said shaft and horizontally-disposed sliding bars connected to said cranks and having their free ends extending 1o into the channel of the plow or runner of the car the said cranks being arranged to project one bar into the path of the plow or runner when the other is Withdrawn substantially as described and for the purpose specified.

In Witness whereof I have hereunto Set my x5 hand in presence of two witnesses.
